Crucial catalyst

The need for early comprehension of scientific concepts in elementary school students is crucial. However, studies have indicated that some students lack a fundamental understanding of such concepts, highlighting the importance of effective teaching methods to improve scientific literacy at an early age.

This study also shows that the g-C3N4/SnO2 heterojunction is a stable catalyst system and superoxide radicals play a crucial role in the photocatalytic NO removal. Since the preparation of the g-C3N4/SnO2 heterojunction reported in this work is straightforward, it can potentially enable the preparation of highly robust visible-light-driven photocatalysts to remove NO pollution.

L-arabinose isomerase (AI) is a crucial catalyst for the biotransformation of D-galactose to D-tagatose. In previous reports, AIs from thermophilic bacterial strains had been wildly researched, but the browning reaction and by-products formed at high temperatures restricted their applications.

A crucial turn in the investigation on NO decomposition occured when Iwamoto et al [1] first found that copper-exchanged zeolites, in particular Cu-ZSM-5 zeolites, were effective catalysts for NO decomposition. These catalysts have been the object of the most active investigations ever since. Due to small pore size of zeolites, the reactant diffusion seems play an important part in the reaction kinetics. This article is aimed to evaluate the role of diffusion by means of activation energy of NO decomposition on Me/Zeolites ZSM-5 and mordenit.
